VALVE Specification of Letters Patent.

Patented July 14, 1908.

Application led October 18, 1907. Serial No. 398,095.

To all whom fit may concern: i

Be it known that I, DELL W. JEWELL, a citizen of the United States,residing at Kalamazoo, in the county of Kalamazoo and State of Michigan,have invented a new and useful Valve, of which the following is aspecification.

This invention relates to lushing valves for use in connection withclosets and its object is to provide a simple device of this characterhaving means whereby the valve is automatically locked when opened,there being means for unlocking the valve and returning it to its closedposition after a predetermined period.

Another object is to provide simple means for regulating the length ofthe flushing periods.

Another object is to provide means whereby the valve can be quicklyreset automatically as soon as closed.

A still further object is to provide novel means whereby leakage withinthe valve may be conducted to the outlet of the valve so that all of theparts will be maintained in operative condition.

With these and other objects in view the invention consists of certainnovel features of construction and combinations of parts which will behereinafter more fully described and pointed out in the claims.

In the accompanying drawingsV is shown the preferred form of theinvention.

In said drawings. Figure 1 is a section through a valve embodying thepresent improvements and showing the positions of the parts while beingset. Fig. 2 is a similar view and showing the positions ofthe partsduringthe flushing operation. Fig. 3 is a transverse section through themain valve.

Referring to the figures by characters of reference, 1 designates asubstantially cylindrical housing having a screw cap 2 which constitutesa closure for one end while the other end of 4the housing'is providedwith a slidable stem 3 having a head 4 at its inner end and a knob orother suitable enlargement 5 at its outer end. This housing isintersected between its ends by a passage 6 extending through a tubularextension 7 designed to be connected to a supply pipe, not shown, andsaid passage also extends through a tubular member 8 projecting fromthe-housing 1 and alining with the extension 7 although preferably ofslightly greater diameter. This extension 8 is designed to be connectedto the bowl in the usual or any preferred manner.

Opening into the extension 7 is a preferably cylindrical housing 9, theouter end of which is preferably closed by means of a screw cap 10.passage 6 and the interior of the housing 9 is established through aport 11 having a valve seat 12 surrounding it. A check valve 13 isiitted within the port 11 and normally rests Communication between theupon the seat 12 and this check valve has a small passage 14 extendingthrough it. A compartment 15 is formed between the housings 1 and 9 andopens into the housing 9 through a passage 16. Adog 17 is fulcrumedWithin compartment 15 and has an arm l 18 extending through the passage16 and into the housing 9. An opening 19 is formed in the bottom ofcompartment 15 and a spring 19 is connected to the dog and bears againstvalve 13 so as to hold the valve f normally upon its seat and the end ofthe dog normally within the opening 19.

A valve 20 is slidably mounted within the housing 1 and has a passage 21therethrough designed to register with the passage 6. A tubularextension 22 is formed with the valve and is slidably mounted within thehousing 1 and this extension has one or more longitudinal grooves 23into one of which extends a screw 24 or other holding device for thepurpose of preventing the rotation of the valve and its extension. Aspring 25 is arranged within the housin@P 1 and projects into valveextension 22. T is spring bears against the screw cap 2 and,

holds the valve 20 normally against one end of the housing so that thepassage 6 is closed by the extension 22 as shown in Fig. 1. A

notch or recess 26 is formed in the extension 22 and is designed toreceive the dog 17 when the valve is moved into open position. The valveis thus locked as shown in Fig. 2 until released in the mannerhereinafter described. A release device in the form of a follower 27 isslidably mounted in housing 9 and a spring l 2S which bears against thescrew cap 10 holds the follower normally against arm 18 as shown bydotted lines in Fig. 2, thus drawing the dog 17 out of engagement withextension 22 and releasing valve 20.

A controlling device 1n the form of a threaded stem 29 engages theextension 7 and has a pointed end 30 in the form of a needle valve whichis designed to project into andpartly close the passage 14 in valve 13.A bypass 81 connects the housings 1 and 9 close to the screw caps sothat any water which may leak past the follower 27 will be free to flowdownward into housing 1 and thence through the groove or grooves 23 tothe outlet extension 8.

When valve 2O is in closed position with extension 22 extending acrosspassage 6 the water under pressure will force valve 18 open against thestress of spring 19. The water will therefore enter the housing 9 andforce the follower 27 toward the screw cap 10 thereby placing the spring28 under stress. -As soon as the pressure becomes equalized at bothsides of the check valve the same will be reset by spring 19/.

To operate the device for flushing purposes stem 3 is pushed inwardlyagainst valve 2O and said valve is therefore shifted longitudinallyagainst the stress of spring 25 until the passage 21 registers withpassages 6 and notch 26 assumes a position opposite the opening 19.Spring 19 will then promptly throw the dog downward into the notch andthe valve will thus be locked open. The water will then be free to flowdirectly from the source of supply through passages 6 and 21 and thespring 2S will force follower 27 longitudinally so as to slowlydischarge 'the liquid contents of housing 9 through the passage 14, thespeed of discharge being regulated by the stem 29. Just prior toreaching the limit of its forward movement the follower strikes arm 1Sand swings dog 17 out of notch 19 whereupon spring 25 promptly shiftsthe valve 20 longitudinally so as to close the passage 6. The water willthen be a ain directed into housing 9 as heretofore escribed and theforegoing operation will be repeated. It will be obvious that byadjustino' the stem 29 toward or from the check valve the time requiredfor the water within housing 9 to escape therefrom can be regulated andthe length of the flushing operation correspondingly controlled.

t will be seen that the device is very simle, durable and eflicient andthat access can e conveniently had to all parts thereof.

What is claimed is:

1. In a flushing valve the combination with a spring pressed supplyvalve and means for actuating the same of means for automaticallylocking the valve in open position, a release device disposed to beactuated in one direction by water under pressure when the valve isclosed, and means for actuating the release device when the valve isopen to unlock the valve.
